What Sets EMISI for Data Centers Apart
Oscilloscopes and Time Domain Reflectometers (TDRs)
- GAO Tek Digital Storage Oscilloscope - Used for capturing high-resolution eye diagrams and jitter analysis across PCIe, USB, and Ethernet links.
- GAO Tek Time Domain Reflectometer - Essential for identifying impedance mismatches, stubs, or reflection points in backplanes and interconnects.
Bit Error Rate Testers (BERTs)
- GAO Tek High-Speed BERT Tester – Used to measure bit error rates across copper and optical interconnects. Compatible with 10G, 25G, and 100G links.
Cable & Connector Testers
Optical Power Meters & Light Sources
- GAO Tek Handheld Optical Power Meter – Verifies optical transceiver output in fiber interconnects (e.g., QSFP28/56/112G).
- GAO Tek Optical Light Source – Paired with the OPM to detect attenuation and validate signal levels over fiber links.
Software & Signal Analysis Tools
Protocol Analysis and Data Visualization
GAO Tek Protocol Analyzer Software (Provided with select testers)
Allows PCIe, Ethernet, and USB protocol decoding, error tracking, and link training analysis. Useful for testing under load or during dynamic configuration changes.
TDR Analysis Software Suite
Available with GAO TDR testers for reflection coefficient plots, fault distance mapping, and impedance profiling. Ideal for PCB and connector analysis.
Eye Pattern Analysis Utilities
Integrated into Digital Storage Oscilloscopes for eye height, eye width, rise time, and jitter breakdown. Helps verify compliance with high-speed signaling standards.
Testing Procedures & Use Cases
Validation of PCIe Gen4/5 Links
Use the BERT and DSO in tandem to assess lane equalization, signal integrity, and BER over x8 or x16 PCIe channels. TDR analysis verifies trace continuity and connector transitions.
100G Ethernet Interconnect Testing
Employ the Optical Power Meter and Light Source for fiber validation, and BERT for verifying frame error rates and jitter across QSFP28 or QSFP-DD modules.
Signal Integrity in PCB and Backplane Traces
TDR tools identify impedance dips and stubs, while oscilloscope eye diagrams confirm timing margins and edge sharpness on differential pairs.
Connector and Cable Testing
Run continuity tests, short detection, and insertion loss measurements using GAO’s cable testers. These helps identify poorly terminated or damaged cables before deployment.
Key Features & Functionalities
- Eye Diagram & Jitter Analysis – Evaluate timing margins, noise floors, and signal clarity.
- Bit Error Rate Testing (BERT) – Quantify data accuracy across serial links during operation.
- S-Parameter Analysis – Analyze insertion loss, return loss, and reflection coefficients.
- Time Domain Reflectometry (TDR) – Locate impedance mismatches or physical discontinuities.
- Cross-Talk & EMI Susceptibility Testing – Detect signal coupling and noise sensitivity in densely routed paths.

Case Study
United State
Case Study 1 – AI Data Center Expansion in Texas
An AI research institute deployed a new data center with over 10,000 nodes and required validation of PCIe Gen5 GPU-to-CPU links. EMISIforDataCenters conducted site-level testing of QSFP-DD cables and ensured jitter and BER levels met design expectations. The project achieved 27% improvement in transmission stability, reducing downtime due to link failures.
United State
Case Study 2 – Cloud Infrastructure Optimization in Oregon
A hyperscale cloud provider experienced erratic data loss in NVMe-over-Fabrics connections. Our team traced the issue to impedance mismatches in board-to-backplane transitions. After targeted High-Speed Interconnect Testing and guided redesigns, signal loss was reduced by over 40%, enhancing throughput across their flash storage arrays.
Canada
Case Study 3 – Telecom Network Upgrade in Ontario
A Canadian telecom company needed to upgrade core routers to support 400G Ethernet. EMISIforDataCenters provided pre-compliance and functional testing of QSFP28 optical transceivers and cables. Our testing helped the client pass their internal benchmarks and cut deployment cycle time by 22%.
